The section II carries a safety valve 30 which Figure 12 is a sectional view on the line l2-I2 communicates with the chamber l6 so as to 50 of Figure 8. relieve excess gas pressure as generated within Figure 13 is a sectional view on the line l3-l3 this section I I. of Figure 8. The section II carries the oppositely disposed Figure 14 is a fragmentary vertical sectional gas delivery pipes 3|, these being fitted with gas view through the pressure operated brake as emfilters 32, while extended from filters 32 are gas 55 outlet pipes 33 (only one of which is illustrated) and each of these pipes is provided with a hand operated cut-off valve 34 and having threaded outer ends 35 for the connection of an acetylene torch or a feed line of a gas lighting system.

The section II has fitted therewith a hand operated valved drain cock 36, so that the chamber l6 can be freed of its contents or sediment or other matter as contained therein.

In Figures 7 to 14 there is shown a modified form of the invention, wherein the lower section 31 is identical to the section II and carries the parts associated with said section I I, there being no variation between these sections II and 31. In lieu of the section III there is provided the section 38 which has interiorly thereof the hopper 39, while beneath the discharge bottom of said hopper 38 is a partition 40, this having a discharge slot 4| therein, the partition being removably fastened between the upper and lower sections of the body, that is, the sections 31 and 38, respectively.

Supported on the section 38 is a hanger 42 supporting a coiled spring motor 43 which, through thegears 44, operates a rotatable valve shaft 45, the same being journaled vertically at the center section 38, its lower end having its bearing in the partition 40. Carried by this shaft 45 is the rotary disk-like valve 46, it having an opening 41 for registration with the opening 4|, these being in thepath of each other so that carbide contained within the section 38 can bedelivered into the section 31 for the generation of acetylene gas. The motor 43 has its' spring 48 hand wound through. the instrumentality of a gear 43 operated from a hand crank 5|), the gear meshing with the gear 5| at the top of the motor 43 and joined with the winding stem 52 for the spring 48, the barrel or casing 53 of said motor having a gear connection 44 with the shaft 45 to operate the same on the rotation of said barrel or casing 53, as will be apparent.

The hopper 39, at the opening 4| in the partition 40, has an overhanging protector ledge or shelf 54 to prevent the gravitation of carbide within the section 38 through the openings 4| and 41 on the registering of these openings during the activity of the valve 46 or the rotation of the same.

Arranged on the section 38 at its top is a cylinder 55 having arranged therein its piston 56, its stem 51 being loosely connected to a braking arm 58 pivoted, at 58, to the hanger 42 and this brake arm, on movement of the piston in one direction, has a braking action on the barrel or casing 53 of the'motor 43 for controlling the action of said motor. Surrounding the stem 51 of the piston 56 within the cylinder 55 is a coiled compression spring 60, the tension of the spring being regulated by an adjusting. member 8| threaded in the end 62 of the cylinder 55, the

member being formed with a wrench-engaging 10 portion 63, so that it can be adjusted to vary the tension of the compression spring 60, and the spring normally tends to move the braking arm away from the motor. The other end of the cylinder has leading therethrough a fluid pipe 15 or conduit 64 which opens into the chamber within the section 31 and thus gas under pressure will flow through the cylinder 55 for action upon the piston 58'to operate the brake arm 58 for the braking of the motor 43 according to the 20 pressure of the gas generated within the apparatus. The gear 49 has ratchet action with a ratchet dog 65 pivotally supported by the hanger 42 It will be apparent that in lieu of the section 25 bide and gas chambers with each other, a rotat- 35 ing shaft for said valve, a spring-wound motor having gear connections with said shaft for operating the same, a gas pressure controlled devicecarried by the casing and communicating with the gas chamber for automatically regulating the motor, said device comprising a pivotally supported braking arm movable to frictionally contact with a moving part of the motor to hold said motor from turning, a piston having a stem connected with the braking arm, a cylinder for the piston, a spring contacting the piston to normally influence the same to move the braking arm away from the motor, an adjustable member for tensioning the spring, and a pipe leading from the cylinder to the gas chamber.
